RESUMO
Psoraleae Fructus is the dried and mature fruit of the legume Psoralea corylifolia. It is warm in nature， pungent and bitter in flavor， and attributive to the kidney and spleen meridians. Its main effect include warming the kidney and assisting Yang， absorbing Qi and relieving asthma， warming the spleen and relieving diarrhea， etc.， and it also can for external use of eliminating wind and freckle. Clinically， Psoraleae Fructus is mainly used for the treatment of impotence due to kidney deficiency， soreness of waist and knees， vitiligo， etc. The existing studies have shown that Psoraleae Fructus has a variety of pharmacological effect， such as anti-tumor， anti-oxidant， anti-bacterial， anti-inflammatory， promoting bone growth and protecting cardiovascular. But at the same time， many studies at home and abroad have found that taking Psoraleae Fructus and its compounds for a long time or in large doses can cause liver toxicity， phototoxicity， nephrotoxicity， etc. The most common is liver toxicity， most of the clinical reports on the toxicity of psoralen are caused by drug-induced liver injury events， which limits the clinical use of Psoraleae Fructus and can't exert its proper therapeutic effect. Therefore， it is particularly important to fully understand the toxicological mechanism of liver injury caused by Psoraleae Fructus and its attenuation methods. In this paper， by consulting the domestic and foreign related literatures in recent years that reported the hepatotoxicity of Psoraleae Fructus， the four aspects of clinical report on liver injury， hepatotoxic components， toxicological mechanisms and attenuation methods of Psoraleae Fructus were reviewed， including bile acid stasis and oxidative stress. The hepatotoxicity of Psoraleae Fructus was discussed in terms of reaction， mitochondrial damage， liver fat deformation， etc.， and the attenuation methods of Psoraleae Fructus were summarized from the aspects of compatibility attenuation and processing attenuation， aiming to comprehensively and objectively clarify Psoraleae Fructus. The potential toxicological mechanism of lipid-induced hepatotoxicity and research progress in attenuation were expected to provide a theoretical basis for further study of Psoraleae Fructus hepatotoxicity and clinical rational use of drugs.
